Title: Frontstruktur eines kraftfahrzeuges
Inventor: BOETTCHER CURD-SIGMUND
IPC: B60R19/12
Filed: 2002-11-02
Abstract: Um die Anforderungen hinsichtlich des Schutzes von Fussgängern in einer Kollision und die Anforderungen hinsichtlich einer leichten Reparierbarkeit von kollidierten Fahrzeugen vereinigen zu können, wird vorgeschlagen, dass die Frontstruktur aus zwei Stossfängern (4, 5) besteht, die zu beiden Seiten über je eine Crashbox (10, 10', 11, 11') an einem Längsträger (2, 3) abgestützt sind, wobei eine Schaumstofflage (25) an einem Querträger (6) des oberen Stossfängers (5) vorhanden ist, die Kräfte bei einer Fussgängerkollision aufnimmt, und wobei die Crashboxen (10, 10') des unteren Stossfängers (4) sich nach vorne über die Schaumstofflage (25) erstrecken, so dass sie die Kräfte bei einer leichten Kollision mit einem anderen Fahrzeug oder einem festen Hindernis unmittelbar nach den Erstkontakt durch Verformung aufnehmen können. Da die Schaumstofflage (25) gegenüber der unteren Crashbox (10, 10') zurückgesetzt ist, wird ein Fussgängerschutz erreicht, ohne dass es zu einer deutlichen Vergrösserung der Fahrzeuglänge kommen muss.

Title: Failsafe device for multistage metal- - stamping machine
Inventor: SCHWARZ WILHELM
IPC: F16P3/00
Filed: 1969-10-07
Abstract: Failsafe device for multistage metal stamping machine. Device is for continuous surveillance of the working of multistage press tool lines. The cut-out device is advanced by a lever attached to the feeding device and contacts a spring loaded slide at the exit end which is pressed against the scrap strip emerging from the machine at the same rate as the feed rate, thus detecting immediately any discrepancy between the two and activating a cut-out switch for stopping the machine. The cutout device is of the inductive type thus cutting down the effective switching-off time to a minimum.

Title: Electrostatic and aerodynamic filter - consists of electrostatic pre-loading, velocity reducing, aerosol precipitating and neutralising zones
Inventor: HAUPT HANS O
IPC: B03C3/12
Filed: 1973-06-08
Abstract: The arrangement is designed to remove from contaminated air or other gas all foreign particles down to the size of aerosols. An improved efficiency has been achieved by a controlled surface charge of the particles. The particles, after being negatively charged, pass a positive field where the laminar flow changes into a turbulent flow by the use of a convex surface followed by a concave surface. The velocity of the media is thereby reduced and this increases the effectiveness of the succeeding precipitating zone.

Title: Plastic junction element packed in sealed envelope - with volatile expand-ing agent so that when envelope is ruptured junction element contracts to form joint
Inventor: RUETTEN RICHARD H
IPC: B29C55/00
Filed: 1973-10-19
Abstract: A plastic pref. flexible junction element (e.g., PVC contg. plastifying agent e.g., di-(2-ethyl-hexyl/phthalate) is pref. extruded in the form of sleeve and is packed in a sealed envelope (e.g., a laminate film of polyethylene, nylon and/or polyethylene terephthalate) contg. a volatile expanding agent (e.g., ethyl, propyl, butyl, amyl, acetate, acetone etc.), which maintains the pref. tubular junction element in an expanded state. When the envelope is ruptured the expanding agent evaporates so that the pref. tubular junction element contracts radially around e.g., the ends of two pipes or pieces of cable inserted into the junction element whereby the pipes or pieces of cable are joined together. The junction element is easy to apply and the degree of contraction of the junction element can be predetermined thereby forming a better joint.

Title: Cleaning of pipes in beer dispensing system - has three-way valve operating of water mains pressure
Inventor: KRONAUGE SIEGFRIED
IPC: B08B9/04

Title: Treatment plant for service water in closed circuits - having sepn. vessels made from preformed concrete sections
Inventor: ROTH LUDWIG DR RER NAT
IPC: C02F3/00
Filed: 1974-03-16
Abstract: A plant for treating recirculated service water by sepn. or neutralisation of accidental contamination has sepn. vessels in the circuit with sealed, removable lids and air outlet pipes. The inlet to the first vessel is above the normal level of the water in it. Water is conveyed from each vessel to the next by a pipe whose inlet lies about halfway between the water level and the floor of the first vessel and whose outlet lies at the level of the surface of the water in the next. The level of water in the vessels is held constant by a level controller which operates a valve in a fresh make-up water pipe connected to the last vessel. The system is comparatively cheap and simple to maintain.

Title: Vehicle door hinge with three flaps and two pivot axes - has flat spring preventing pivoting about second axis until door is open
Inventor: MELZER KURT
IPC: E05D3/06
Filed: 1974-03-30
Abstract: The door hinge on the vehicle comprises three flaps, one attached to the door, one attached to the vehicle, and one in the middle which is biassed in the open position by a spring which is pre-stressed when the door is closed. The spring is pref. a flat spring. A first flap is screwed to a hollow support, and a second flap is screwed to the door which is provided with a stop cooperating with the central flap to prevent pivoting of the door beyond the closed position. The flat spring acts on the central flap causing the door to pivot about an axis into the position shown in dot-dash lines, whereupon the door can be further pivoted.

Title: Fixed modulation keyboard - for musical instruments with piano type key-boards, has rotatable pressure transmission for adjacent notes
Inventor: MARCHNER OTTO
IPC: G10C3/28
Filed: 1974-04-05
Abstract: A fixture modulation keyboard for instruments e.g. pianos, accordions, with piano-type playing keyboards has black and white keys operating on a pressure transmission piece which is made such in such a way that it can be swivelled round by an external means to strike alternate notes depending on its positioning in cover plates. The swivelling mechanism is installed in the spaces incorporated in the device. The playing of accidental notes is thus made easier since they can be played on the white keys without having to stretch out for the black ones. It is possible to cover all eventualities, a restriction being a question of cost, nature of instrument and its range of scales.
